About an hour before my wedding, I sat in a waiting area designated for the groom in a small house to the side of the venue. I sat nervously in the window watching the guests arrive. I was nervous as hell and began to get myself dressed when my soon to be mother-in-law came up to see how I was making out. I was pretty much dressed in my tux by then, and she helped me straighten everything out so I didn't look like a mess at the altar. I don't know why, but as she was tugging at the cummerbund and aligning my button down shirt, I suddenly got very excited. For a second it was the most embarrassing moment of my life, standing there minutes away from my wedding with a throbbing problem staring right at my soon to be mother-in-law. She didn't say a word. She just smiled at me with an "ahh, poor baby” look, and in what seemed to be one swift motion, she undid my fly and began to relieve me manually right there, standing in the window overlooking our wedding guests arriving. I was speechless, nervous, and scared yet at the same time incredibly turned on. After a few minutes of her tugging at me, she bent over to give it a little oral, and that’s all it took. She smiled at me and zipped me back up. She patted me on the ass and said, "Don't be late," and walked out of the room. We have never done anything like that since and never even spoke about it. I probably masturbate once a week thinking about that five minutes of my life.
